Switching the boiler on: Set the rotary switch "Operating mode" (Fig. 180,8) to summer operation
"40 °C" or "70 °C" (Fig. 180,1) or to winter operation "Heater and boiler"
(Fig. 180,4).
The indicator lamp "Operation/fault" (Fig. 180,5) lights up green.
The symbol of the selected operating mode lights red.
Switching the boiler off:
Turn the rotary switch "Operating mode" (Fig. 180,8) to "OFF"
(Fig. 180,10).
The indicator lamp "Operation/fault" (Fig. 180,5) goes off.
Frost protection mode In frost protection mode, only the boiler is protected against frost. The water
pump and the water pipes are not protected against frost.
In frost protection mode, the device works like in the "Heater and boiler" oper-
ating mode. However, the water in the boiler is not heated to 60 °C, but rather
only slightly warmed.
The boiler is not automatically emptied at ambient temperatures below 6 °C.
Filling/emptying the boiler The boiler can be supplied with water from the water tank.
Filling the boiler with water:
Switch on 12 V power supply on the panel.
At ambient temperatures below 6 °C, switch the rotary switch "Operating
mode" (Fig. 180,8) to summer operation or winter operation "Heater and
boiler" so that the safety/drainage valve is not opened.
Set all the water taps to "Hot" and open them. The water pump is turned
on. The warm water pipes are filled with water.
Keep the taps open until the water flowing out of the taps has no bubbles
in it. This is the only way to ensure that the boiler is full of water.
Close all water taps.
Emptying the boiler:
Switch off the water pump's power supply on the panel.
Set all the water taps to "Hot" and open them.
Switch and hold the rotary switch "Operating mode" (Fig. 180,8) for at least
5 seconds at position "Emptying boiler" (Fig. 180,9) on the operating unit.
The boiler is drained to the outside by the safety/drainage valve.
Indicator function
"No water"
When the "Heater and boiler" operating mode is selected, although the boiler
is empty, the indicator lamp "No water" (Fig. 180,3) flashes. In this case, fill the
boiler with water.
Frost protection mode consumes fuel and electricity. In frost protection
mode make sure that sufficient fuel is available and that the battery is
charged.
Further information can be obtained in the manufacturer's instruction
manual.
For further information about the use of the boiler see section "Boiler".
